Be alert for browser update scams

IT has received several reports of University computer users seeing pop-up windows and redirects to fake "update your Web browser" pages that can download malware onto your computer. Reports indicate that these fake pages may be appearing as a result of counterfeit or corrupted ads when you visit an otherwise legitimate site.

Internet Explorer (IE) users report that IE is catching this threat automatically.

To keep up with the latest security patches, it is important to keep your Web browsing software (Firefox, IE, Chrome, Safari, Opera, etc.) current. However, you should only trust updates from official sources:

  1. An update notification from within your computer's Web browsing software,
  2. An update notification from your computer operating system's auto-update function,
  3. An update you have downloaded from the Web browser's official Web site.
